T0 @ZZ zul/00711, it vit/ty concern:

Be it known that I, ISAAC E. PALMER, a citi- Zen of the United States,and a resident of Middletown, in the county of Middlesex and State ofConnecticut, have invented a new and useful Machine for ExtractingLiquid from Fabric, of which the following is a specification.

My invention relates to a machine for extracting liquid from fabric, andmore particularly to means for utilizing centrifugal force in connectionwith the wringing of a rope of fabric to free the fabric from liquid.

A practical embodiment of my invention is represented in theaccompanying drawings, in which- Figure 1 is a top plan view of themachine. Fig. 2 isa longitudinal vertical section in the plane of theline A A of Fig'. 1, and Fig. 3 is a transverse section in the plane ofthe line B -B of Fig. 2.

The bed of the machine is denoted by 1. It may be supported in anysuitable manner-as, for example, upon legs 2.

From the bed 1 standards 3 and 1 uprise, and in the said standards 3 anda bearing's 5 and 6 are formed for the reception of the hollow trunnionsT and 8 of what I am pleased to term the "centrifugal frame. Thiscentrifugal frame is composed of a pair of side plates 9 and 10, fixedto or formed integral with the trunnions 7 and 8 and held spaced apartto receive between them the rollers for guiding therope of fabricthrough the frame. ln the present form of my invention l use four ofthese rollers, two of them (denoted, respectively, by 11 and 12) beingjournaled in the upper and lower parts of the centrifugal frame invertical alinement and another two (denoted, respectively,by 13 and 14)being mounted in the opposite ends of a vibrating frame 15, mounted, bymeans of trunnions 16 17, extending' outwardly from the opposite sidesof the frame, between the sides 9 and 10 of the centrifugal frame. Thevibrating frame is made in open-loop form, so as to permit the rope offabric to pass between its opposite sides, and the rollers 13 1&1,carried by the vibrating' frame, are in such position as to hold therope of fabric in proximity to the rollers 11 12, journaled in thecentrifugal frame, and, fur- (No model.)

thermore, as the result of the centrifugal force of the centrifugalframe when rotated at a high speed the rollers 13 and 14 will have atendency to move away from the axis of rotation of the centrifugalframe, and this will cause the vibrating f rame carried by thecentrifugal frame to rock in a .direction to press the rollers 13 and 14toward the rollers 12 and 11, respectively, and so squeeze the rope offabric passing between them. This squeezing' force may be increased, ifdesired, by a spring so arranged as to normally rock the vibrating-frameto press the rollers 13 14 toward the rollers 12 and 11, respectively.Such a spring is indicated in Fig. 2 as a bar-spring 18, fixed at oneend at 19 to the inner face of one of the sides of the centrifugal frameand with its free end pressing on the side of the vibrating' frame. Itis to be understood that this spring is a feature which may 0r may notbe used, according to the pressure required in any particular instance,as only one of many obvious forms of applying spring-pressure to thevibrating frame.

The centrifugal frame is rotated by means `of a band-pulley 20 on theextended end of the trunnions 8, driven from a suitable source of power.(Not shown.)

The rope of fabric (denoted by 21) is fed to the centrifugal frame froma series of gripping-rollers, three in number, (denoted by 22 23 24,)mounted in a suitable frame 25, upris- Y ing from the bed 1 at one endthereof, and is drawn from the centrifugal frame by a corresponding setof gripping-rollers 26 27 28, mounted in a suitable frame 29 at theopposite end of the bed 1. In the form in which my invention is herepresented the rollers at the discharge end are relied upon to draw thefabric through the machine, although it is obvious that the rollers atthe opposite end might be power-driven, if so desired. The fabric afterpassing' between the inlet-rollers in the form of a flat strip passesthrough the hollow trunnions 8 and thence under and partially around theroller 14: in one end of the vibrating frame 15, thence between theroller 21 and the roller 11 up, over, and around the roller 11 and downbetween the sides of the vibrating' frame 15 under and around the rollerY twisting the fabric intermediate of said grip- 12, thence between theroller 12 and the roller 13 and over and partially around the roller 13,and thence through the hollow trunnion 7 to the discharge-rollers.

The centrifugal frame driven at ahigh speed of rotation while the ropeof fabric is being drawn through produces a tight twist and wringingeffect upon the rope of fabric in proximity to the rollers at the inletend and throughout that portion of the rope of fabric between theinlet-rollers and the centrifugal frame, and this twist is taken out asthe rope of fabric leaves the centrifugal frame and passes through thehollow trunnion 7 to the discharge-rollers.

The rope of fabric in passing through the centrifugal frame is carried aconsiderable distance radially away from the axis of rotation of thecentrifugal frame in opposite difirections from the axis, and so isbrought under the influence of a powerful centrifugal force because ofthe high rotation of the centrifugal frame, which has a tendency tothrow the liquid away from the rope of fabric andremove all free liquidfrom the fabric. This centrifugal action follows closely upon thewringing effect produced by the twist of the fabric as it approaches thecentrifugal frame, so that all liquid which is wrung to the surface willbe thrown off. i

lVhat I claim is- 1. The combination with means for gripping a rope offabric at points spaced apart and causing the said rope of fabric topass through the said gripping devices, a rotary part for ping-pointsand means for guiding the fabric laterally away from the axis ofrotation of the said rotary part as it passes through said grippingdevices.

' 2. The combination with inlet-rolls and outlet-rolls for conducting arope of fabric, of a said rotary part while engaged with said rotarypart.

3. rlhe combination with inlet and? outlet rolls, for conducting a ropeof fabric, of a rotary frame provided with hollow trunnions rotary framelocated intermediate of said gripping-points and provided with hollowtrunnions, of rollers mounted in said frame radially distant from theaxis of rotation of the said frame," a vibrating frame mounted in saidrotary frame, rollers mounted in said vibrating frame and means fordirecting a rope of fabric through the said rotary frame in engagementwith the aforesaid rollers.

5. The combination with means for gripping a rope of fabric at pointsspaced apart and a rotary frame located intermediate of saidgripping-points and provided with rollers located radially distant fromits axis of rotation, of a vibrating frame mounted in said rotary framein position to rockin a plane of the axis of rotation, rollers mountedin the opposite ends of said vibrating frame and means for directingarope of fabric into engagement with the said rollers between the saidrollers mounted in the rotary frame and the rollers mounted in theVibrating frame whereby the rocking of the vibrating frame undercentrifugal force of rotation of the rotary frame will squeeze thefabric between the rollers.

Intestimony that I claim the foregoing as my invention I have signed myname, in presence of two witnesses, this lst day of January,

ISAAC E. PALMER. Witnesses:
